So we have upgraded our game to 4.11 to gain all those sweet eyeball effects and what not.
But we have run into a problem with the transfer over to a new version.
The gun has disconnected from my character and I got this error.
Please help
That node is deprecated, meaning it should no longer be used (It is outdated), you need to use the standard cast node, so ‘Cast to ______’. That node hasn’t been needed since UE 4.1 I believe 
Thanks That fixed that problem. I am not seeing any other problems in the blueprint, but my gun is still detached from my character and my H.U.D. is gone. Any ideas what is going on?
Do you use the ‘instigator’ variable at any point in the character and HUD code?
